Countdown JS is a JavaScript class that displays (and updates) the time left until a time specified by the user. Times can be provided in any time units, and they will be recalculated to the specified time units. It is possible to use a format string to specify which units or text will appear in the displayed countdown and which text must be hidden if a certain unit reaches 0. Format strings also accept HTML tags, thus providing you the ability to format your countdown as you desire.
